Maybe we should encourage greenhouse gasses (and therefore anthropogenic global warming) to compensate for the postulated coming 30 year cold period.  Maybe we need to burn more coal.    
 
 I personally do not know if the next few decades will be warmer or colder, I do know that there is disagreement.  I've also read reports that indicated the numbers supporting GW were "fudged".  That disparity tells me to cover the possibility of a cooling trend as well the much more discussed global warming.
